A case of adenoid cystic carcinoma of the cervical trachea is presented here. The case was a 61year-old woman with discomfort in the laryngeal region. Progressive recurrent nerve palsy and swelling of the posterior tracheal wall were revealed by X-ray film, suggesting a malignant tumor. The patient underwent resections of the lower pharynx, larynx, a part of the cervical esophagus and the entire thyroid gland in conjunction with right radical neck dissection followed by reconstruction with the free intestinal graft. During abdominal surgery, metastatic lesions of the liver were discovered. Histrogical examination revealed an adenoid cystic carcinoma. Adjuvant chemotherapy was performed with CDDP and 5-FU. Postoperative irradiation will be indicated.<BR>Primary malignant tumors of the trachea are rare. Adenoid cystic cartinoma is the second most common cancer of these. Although this tumor is classified as a low-grade malignancy, early diagnosis is important because of the high probability of multiple organ metastasis.
